As an aside of how SW can go off the rails without it being obvious until you get there:
There's an actually pretty interesting and genuinely well-done post-apocalypse third party setting/plot point game for SW, now updated to SWADE (though its not out yet I believe) called Broken Earth. Broken Earth was apparently originally done as something to be run with 5e (because it always goes well to try and use a D&D derivative for things far outside its bailiwick) and at one point the PCs can get some high-quality armor. Most likely in the D&D5e version, this was relatively high AC--but it was till dealing with the D&D style combat system, the swings in D20s were likely still producing fairly regular hits after the PCs got that.
When the author, who wasn't, as far as I can tell, exceptionally familiar with SW converted it to that, he made the armor into Combat Armor. That's way off what you expect to get any traction on with a mixture of primitive weapons, black powder, and an occasional hunting rifle and the like; and unlike various ballistic cloth armors, its still full value against melee weapons. The net effect was that once it got to that point in the campaign, the PCs were semi-invulnerable to most attacks, with a negative impact on the rest of the campaign, all because of a simple error in design.
(I pointed out the problem to the author and the new version will have ballistic armor instead, which will serve the same purpose in the campaign while not being excessive).
